DASH

[Dash] specifies the line type. There are 4 types of line which can be drawn in PHOTON.
Type 0 is for a solid line.

Dashed lines in AUTOPLOT

If a plot contains several data elements, you may wish to distinguish them by using
various kinds of dashed lines. This may be effetced by way of by the DOTn command, which
is used in the same way as the PLOT command. The n in this command represents a single
digit and must not be preceded by a space. The value of n determines the type of dashed
line to be used, as follows:

Some of the dashed lines generated by these commands may differ slightly, depending on
the graphics terminal used.

Suppose you wish to plot three sets of data; the first drawn with solid lines, the
second with dashed lines and the third with small circles at the data points. You achieve
this by the following sequence of commands:

DATA; PLOT; DATA; DOT; DATA; BLOB; SCALE

The final SCALE ensures that all of the data elements will be shown within the axis
window. As another example, suppose that there is one data element to be shown by small
circles, and three more to be shown by finely-dashed lines. The following command sequence
is now required:
